hi, i am looking for movie i saw more than 15 years ago, from late 80s or early 90s, its about alien hunter or parasite possessing humans (i am not sure) and killing humans, there was this amazing scene, with amateur metal band (long haired dudes in denim jackets) rehearsing in garage or basement some badass song with lyrics "kill your mama, kill your papa" and they are killed by that nasty alien...anyone know name of that movie or band???
